- A glass bottle
- A peeled hard boiled egg
Ok, so that list includes fire, glass, and a seriously major allergen for my daughter. Super. If you replaced "Paper" with "A child molester" it would be the perfect quadfecta of child danger. I thoughtfully considered this activity and realized that the alternative could very well be a game of "Daddy, I'll pretend to be the baby mouse and you'll be the mommy mouse!"
I found an empty wine bottle, a lighter, a few eggs, and a newspaper. Experiment on.
The instructions said to light the paper on fire, drop it into the bottle, and then place the hard-boiled egg on top of the bottle. The idea was that the burning paper would consume the oxygen in the bottle, creating a vacuum, which would then suck the egg down into the bottle. I tried to explain the physics of this to Daisy, but it's not easy to explain the concepts of vacuum and atmospheric pressure to a six year old. Luckily the lecture had a big finish, when I brought it home with "Look, fire!"
I am pleased to report that my daughter can touch eggs without having a reaction. I am displeased to report that this experiment is really hard to perform if the glass bottle in question is long-necked. By the time I got the flaming paper down into the bottle, the fire was extinguished, resulting in a unspectacular yet sooty egg.
We almost nailed it on one of the iterations, but the vacuum merely broke the egg apart, only sucking a piece of it down into the bottle. The instructions failed to mention that burnt egg doesn't smell so good.
Science is hard.
